Thales ProtectServer 3 HSMs – PTK 7.3.0/FW 7.03.00 now available

We are pleased to share that ProtectToolkit (PTK) 7.3.0/FW 7.03.00 is now available. With this release, ProtectServer 3 HSMs are transitioning from FIPS 140-2 to FIPS 140-3 compliance. FIPS 140-3 Level 3 validation is still pending; however, with the new firmware version 7.03.00 and onwards, ProtectServer 3 HSMs will conform with the new FIPS 140-3 Level 3 standards.

Thales highly recommends reading the release advisory notes before upgrading to firmware 7.03.00 or newer. Firmware versions older than 7.03.00 remain compliant with FIPS 140-2 Level 3 standards, with firmware version 7.01.02 being the latest FIPS 140-2 Level 3 validated.
